Fuel-Efficient Driving Strategies for Heavy-Duty Vehicles: A Platooning Approach Based on Speed Profile Optimization

Table 3

The average ratio between the fuel consumption obtained in an online run and that obtained in a long offline run, for four different road profile lengths (5, 10, 15, and 20 km), normalized by the value obtained for the 10 km case. The running time for the online runs was 3.5 minutes in the case of 5 km road profiles, 7 minutes for the 10 km road profiles, and so on.
